PURPOSE: To effectively recognize a speech by allowing a pattern matching unit to analyze a speech signal through the use of both of the output of a neural network unit and a vocabulary identifying output so as to output a signal expressing a word in the speech. CONSTITUTION: A memory 17 includes speech information concerning the vocabulary of recognizable words and the pattern matching unit 16 identifies a boundary between different words and in order to give the first display of the word in the speech, compares stored vocabulary and the speech signal to execute the first analysis of the speech signal. Then this device includes the neural network unit 20 connected with the pattern matching unit 16. This pattern matching unit 16 executes the second analysis of the speech signal utilizing both of the output of the neural network unit 20 and vocabulary identification from first analysis and gives an output signal expressing the word in the speech at least from second analysis. |
